Hello people ![Smile :oldsmile: :oldsmile:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/smile.gif)
I would like to discuss one issue here.
Let’s imagine that I am looking to the sphere:
I can clearly see that it sphere, not cylinder, or cube, or submarine, or dinosaur.
So what I see is objective truth.
But how do we generally see the objects? We have got two eyes, the visual information flows from them to thalamus and then to visual cortex in occipital lobe. Extremely complex processes occur there and in the result I/we see the sphere in front of me.
Now imagine that visual cortex is arranged in a bit different way and in principle this was possible – the evolution could go in a bit different way. Let’s assume that visual cortex has 9 layers, that visual information flows to layer 1 (outermost layer), then it goes to layer 5, then to 7 and etc. We can imagine as many things as we wish.
But eventually I would see the same sphere in front of me, right? If I doubt what kind of object do I have in front of me I can touch it and I can be sure that it is sphere and not cylinder, or cube, or submarine, or dinosaur.
So, my question is – our current pattern of our visual system/cortex is the only possible one that enables us to see objects objectively as they are in reality? Or perhaps other patterns are also possible? Under different kind of visual system we would see other objects (cube instead of sphere for example)?![Roll Eyes :oldeyes: :oldeyes:](https://www.physicsforums.com/styles/physicsforums/xenforo/smilies/oldschool/rolleyes.gif)
